ATTORNEY$ SEISMOGRAM TIMING LINES NUlVlBERlNG APPARATUS Denny P. Schafer, Houston, Tex., assignor to Willis L. Looney, Orange, Tex.

This invention relates to seismographic apparatus, and more particularly to an improved device for imprinting timing numbers on seismograms.

A main object of the invention is to provide a novel and improved means for imprinting time numerals on a seismogram, said means being simple in construction, being easy to operate, and enabling the desired numerals to be imprinted on a seismogram in accurate registry with the points on the seismogram corresponding to said numerals.

A further object of the invention is to provide an improved apparatus for imprinting timing numerals on a seismogram, said apparatus being inexpensive to construct, being durable in construction, and providing a substantial saving in the time and effort required to number the timing lines on a seismogram.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 1 is a top view of an improved apparatus constructed in accordance with the present invention, shown set up for use.

Figure 2 is a front elevational view of the apparatus of Figure 1.

Figure 3 is a fragmentary bottom plan detail view of the end portion of the printing bar employed in the apparatus illustrated in Figures 1 and 2.

Figure 4 is a perspective view of the adjustable seismogram guide abutment member employed in the apparatus of Figures 1 and 2.

Figure 5 is a side elevational view of the apparatus shown in Figures 1 and 2.

Figure 6 is an enlarged cross sectional detail view taken on the line 66 of Figure 1.

Figure 7 is a fragmentary top plan view of the printing bar and the underlying seismogram illustrated in Figure 1, said view being shown to a considerably enlarged scale as compared with Figure 1, the intermediate portions of the printing bar and seismogram being broken away.

Figure 8 is a vertical cross sectional view taken on the line 88 of Figure 7, showing the overlying relationship of the inking sheet with respect to the seismogram.

Referring to the drawings, 11 designates the apparatus generally, said apparatus comprising a fiat rectangular support 12 of any suitable rigid material on which is disposed a straight abutment element 13, said abutment element comprising an upstanding rigid plate member 14 having secured to its ends the angle brackets 15, 15, said angle brackets having the depending flanges 16, 16 frictionally engaging the opposite edges of the support 12 to adjustably secure the abutment member 13 with the plate element 14 disposed parallel to the front and rear edges 17 and 18 of the support 12.

Designated at 19, 19 are respective lever arms which are hinged to the rear marginal portion of support 12 adjacent the rear edge 18 by hinge brackets 20, 20, the hinge pins 21, 21 extending through the brackets 20 and through the United S at s, Paten lQiice ends of the levermember 19, 19 being in alignment and being disposed along an axis parallel to the upstanding thereof illustrated in Figures 5 and 6.

Secured to the bottom surfaces of the end portions of the arms 19 are the respective aligned channeled brackets 24, 24 in which is adjustably secured the printing bar 25, said printing bar extending parallel to the axis of rotation of the respective arms 19, 19 and being provided on its bottom surface with the uniformly spaced, depending timing numbers 26, said timing numbers overlying the'support 12 outwardly of the upstanding plate element 14 of the abutment member 13, namely, to the left of said plate element, as viewed in Figure 6.

The timing numbers 26 may be adjusted in a direction parallel to the plate 14 by shifting the timing bar 25 in the channeled bracket elements 24, said bracket elements frictionally engaging the printing bar to hold said printing bar in adjusted position. i

As shown in Figures 3 and 6, the printing bar 25 1s provided adjacent its zero point with a depending, outwardly projecting resilient index element 27 depending below the plane of the bottom surfaces of the numerals 26 and be1ng engageable with the support 12 prior to the engagement of the numerals 26 therewith when the printing bar s moved downwardly toward said support.

In using the device, the seismogram, shown at 28 1s placed on the support 12 with its edge in abutment with and a sheet of suitable printing material, such as carbon paper or the like, shown at 29, is placed over the seismogram with its edge in abutment with the upstanding plate element 14 of abutment member 13. The arms 19, 19 are then depressed to engage the printing bar 25 against the sheet 29, firm pressure being applied to the printing bar so that the impressions of the numerals 26 will be transferred to the seismogram through the printing sheet 29. Obviously, the sheet 29 may consist of an inking sheet or other suitable transfer means for causing the impressions of the depending numeral elements 26 to be transferred to the seismogram.

Obviously, the above procedure may be varied somewhat, as for example, the zero line on the seismogram may be aligned with the index element 27 by moving the seismogram along the plate element 14 rather than by moving the printing bar through the channel elements 24, as above described.

It will be further understood that printing bars carryinvention except as defined by the scope of the appended claims.

What is claimed is:

1. Means for imprinting time numerals on a seismogram comprising a fiat support, a straight abutment element of substantial length on said support for engagement with an edge of a seismogram disposed on the outer portion of said support, lever means pivoted to said support for rotation around an axis parallel to said abutment element, channel means secured to the underside of said lever means, and a printing bar carrying depending, uniformly spaced time numerals on its under side, means slidably supporting said printing bar in said channel means for adjustment parallel to said abutment element in a position overlying said outer portion of the support, and resilient means secured to said printing bar and depending below the time numerals thereon, said resilient means being engageable with the support prior to the en gagement of said time numerals therewith when the printing bar is moved downwardly toward said support.

2. Means for imprinting time numerals on a seismogram comprising a flat rectangular support, a straight abutment element of substantial length disposed on said support for engagement with an edge of a seismogram disposed on the outer portion of said support, depending flange elements on the ends of said abutment element frictionally engaging the ends of said support, whereby said abutment element may be adjusted transversely on said support, a plurality of levers pivoted to said support for rotation around an axis parallel to said abutment element, aligned channel members secured to the undersides of the free end portions of said levers, and a printing bar carrying depending, uniformly spaced time numerals on its under side, means slidably supporting said printing bar in said channel members for adjustment parallel to said abutment element in a position overlying said outer portion of the support, and resilient means secured to said printing bar and depending below the time numerals thereon, said resilient means being engageable with the support prior to the engagement of said time numerals therewith when the printing bar is moved downwardly toward said support.

3. Means for imprinting time numerals on a seismogram comprising a flat rectangular support, a straight abutment element of substantial length disposed on said support for engagement with an edge of a seismogram disposed on the outer portion of said support, depending flange elements on the ends of said abutment element frictionally engaging the ends of said support, whereby said abutment element may be adjusted transversely on said support, a plurality of levers pivoted to said support for rotation around an axis parallel to said abutment element, aligned channel members secured to the undersides of the free end portions of said levers, a printing bar carrying depending, uniformly spaced time numerals on its under side, means slidably supporting said printing bar in said channel members for adjustment parallel to said abutment element in a position overlying said outer portion of the support, spring means biasing said lever means upwardly, and a depending, resilient index element secured to said printing bar and depending below the time numerals thereon, said index element being engageable with the support prior to the engagement of said time numerals therewith when the printing bar is moved downwardly toward said support.
